# Math Help - Fourth-Order Runge-Kutta Method

1. ## Fourth-Order Runge-Kutta Method

Use classical fourth-order Runge-Kutta Method with $h = 0.2$ to approximate the solution to the initial value problem:

$y' = -20y$
$y(1) = 3$

at $x = 1, 1.2, 1.4$

2. If you know what the "fourth order Runge-Kutta" method is, this should be just an arithmetic problem. What have you done on it?
